Answer:
x=-55
Step-by-step explanation:
(2)(4)+(11)(3)+(13)(2)+2x−8=x+4
Simplify both sides of the equation.
8+33+26+2x+−8=x+4
Combine like terms
(2x)+(8+33+26+−8)=x+4
2x+59=x+4
2x+59=x+4
Subtract from both sides
2x+59−x=x+4−x
x+59=4
Subtract 59 from both sides
x+59−59=4−59
x=−55
A coral reef grows 0.19m every week. How much does it grow in 14 weeks? Write your answer in centimeters.
Answer:
The coral reef grows 266 cm in 14 weeks.
Step-by-step explanation:
Lets convert 0.19 meters to centimeters.
1m= 100cm
0.19m×100= 19 cm
It grows 19 cm every week, so:
[tex]\frac{1w}{19 cm} *14 =\frac{14w}{x= 266 cm}[/tex]
So, the coral reef grows 266 cm in 14 weeks.

Answer:
w=4
Step-by-step explanation:
First, we can simplify the equation.
28=14w-7w
28=7w
Then, we can divide by 7 on both sides of the equation.
28/7=7w/7
4=w
Finally, we know that x equals 4.
Answer:
w =4
Step-by-step explanation:
28 = 14w - 7w
Combine like terms
28 = 7w
Divide both sides of the equation by the same term
28/7 = 7w/7
Simplify
w = 4

The Sugar Sweet Company is going to transport its sugar to market. It will cost $6500 to rent trucks, and it will cost an additional $125 for each ton of sugar
transported.
Let C represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this
equation to find the total cost to transport 18 tons of sugar.
Answer:
$ 3750 = truck rental; $125 per ton of sugar transported
C is cost; S is number of tons transported
Equation relating C to S would be a linear equation like y = mx + b
C = 125S + $3750
This equation would be graphed in the first quadrant only
you would start with your y-intercept at (0, 3750)
As x increases by 1, your y increases by 125 yielding these points:
(1, 3875) (2, 4000) (3, 4125) etc.
This shows that for each increase by one ton of sugar, the cost goes up $125

The perimeter of a square is 48 millimeters. What is its area?
Explanation:
The perimeter is 48 mm. We divide that by 4 to find the side length of the square, since each side is the same length.
48/4 = 12
Each side is 12 mm long.
This means the area of this square is 12^2 = 12*12 = 144 square mm

a theme park had 1099 vistiors in three day.
there were twicw as many vistiors on saturday.
than on friday.there were 234 more vistiors on sunday than on saturday.
how many visitors
Answer:
Number of visitors on Friday = 173
Number of visitors on Saturday = 346
Number of visitors on Sunday = 580
Step-by-step explanation:
Total number of visitors over 3 days = 1099
Let x = number of visitors on Friday
If there were twice as many visitors on Saturday than on Friday, then
⇒ number of visitors on Saturday = 2x
If there were 234 more visitors on Sunday than on Saturday, then
⇒ number of visitors on Sunday = 2x + 234
Create an expression for the total number of visitors and solve for x:
⇒ x + 2x + 2x + 234 = 1099
⇒ 5x + 234 = 1099
⇒ 5x = 865
⇒ x = 173
Substitute found value of x into the expressions for each day:
⇒ Number of visitors on Friday = 173
⇒ Number of visitors on Saturday = 2 x 173 = 346
⇒ Number of visitors on Sunday = (2 x 173) + 234 = 580

Find the surface area of the cylinder. Use 3.14 for pi. Do not round the answer.
Question 1 options:

453.25
471
254.12
Answer:
C) 471
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
r = 5
h = 10
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5)(10) + 2(3.14)(5²)
SA = 314 + 2(3.14)(25)
SA = 314 + 157
SA = 471

The average monthly bill for wireless telephone subscribers from 1985 to 2008 can be modeled by B(x) = -1 463x + 95.514, where x is the number of years after
1980. If this model remains valid, in what year will the average monthly bill be $38.46?
If the model remains valid, in the year 2,019 the average monthly bill will be $38.46
How to use the linear equation?
The linear equation that models the average monthly bill is:
B(x) = -$1.463*x + $95.514
We now want to know when the average monthly bill will be $38.46, then we need to solve:
B(x) = $38.46 = -$1.463*x + $95.514
Solving this for x, we get:
$38.46 = -$1.463*x + $95.514
$1.463*x = $95.514 - $38.46 = $57.054
x = ($57.054)/($1.463) = 39
And x is the number of years after 1980, then this will be in the year:
1980 + 39 = 2,019
Then, if the model remains valid, in the year 2,019 the average monthly bill will be $38.46

Put the following equation of a line into slope-intercept form, simplifying all fractions.
15x-9y= −9
The equation of a line in slope intercept form is given by:
y = mx + c
The equation 15x - 9y = -9 of a line into slope-intercept form after simplifying all fractions is y = (5/3)x + 1
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
y = 2x - 3
y = 3x + 4
We have,
15x - 9y = -9
We will rewrite in the slope-intercept form of y = mx + c.
15x - 9y = -9
Subtract 15x on both sides.
-9y = -9 - 15x
-9y = -15x - 9
Divide both sides by -9.
y = (-15x - 9) / -9
y = (15/9)x + 1
y = (5/3)x + 1
Slope = m = 5/3
y-intercept = 1
This is in the slope-intercept form of y = mx + c.
Thus,
The equation 15x - 9y = -9 of a line into slope-intercept form after simplifying all fractions is
y = (5/3)x + 1

h (-5) = 1/4(-5)^2 + 4
h (-5) = 1/4(25) + 4
h (-5) = 41/4 or 10.25

Step-by-step explanation:
The cost function for Julia's clothing store per month is 14.60n +970
What is function?A function is defined as a relation between a set of inputs having one output each.
Given that, Julia is opening a clothing store. She plans to start by selling sweatshirts. It costs her $10.50 for each sweatshirt, $4 per box for the shirts, and $0.10 a bag. Julia also spends $900 on rent, $40 on electricity, and $30 on advertising each month.
There are two types of cost Julia have,
The variable cost that is not fixed and depend on how many shirts she's making, = $10.50+$4 +$0.10 = $14.60
Let she makes n shirts, so cost = $14.60n
And the second one is fixed cost that is cost she is spending on rent, electricity and advertising, = $900+$40+$30 = $970
Therefore, cost = 14.60n +970
Hence, the cost function for Julia's clothing store per month is 14.60n +970

Answer:
hi and hello and welcome to the internet
Answer:
AOS: -4
Vertex: (-4,2)
X-intercepts: (-6,0) , (-2,0)
Y-intercept: (0,6)
Step-by-step explanation:
The Parabola opens upwards (as can be seen in the image.) To find the AOS (Axis of Symmetry) first identify the vertex (-4,2) and take the X value of it.
So the AOS is x = -4
Vertex is (-4,2)
The x-intercepts are seen in the graph, (-6,0) and (-2,0)
The y-intercept is where the parabola first touches the Y-axis, which as can be seen is, (0,6).

A motorboat travels 464 kilometers in 8 hours going upstream and 540 kilometers in 6 hours going downstream. What is the rate of the bot in still water and what is the rate of the current?
Answer:
rate 72 mph; current 16 mph
Step-by-step explanation:
to find the rate of the boat and the current we can model the equation like this
let r = rate
let c = current
8(r - c) = 464
6(r + c) = 540
8r - 8c = 464
6r + 6c = 540
r - c = 58
r + c = 90
then you could use elimination to find r
2r = 148
r = 74
the rate is 74 mph
then plug it in
the current is 16 mph

Since there is no parenthesis or exponent, we go with multiplication as the first option in this problem. 16 x 3 and 3 x 3. 16 x 3 = 48, and 3 x 3 = 9. Since there is no Division on here, we will go the addition, where you add all the numbers up. 48 + 4 = 52 + 9 = 61

Answer:
A, the first option, 49 square cm
Step-by-step explanation:
[] To know
-> A squares sides are all the same size
-> The area of a square can be found by finding L * W
[] Solving
-> We can use the points given to solve for one side, EF, of the square
-> Both the x coordinates are the same, so we can subtract the y values as they are on the same line.
6 - -1 = 6 + 1 = 7
-> Now for the area
7 * 7 = 49 square cm

Mackenzie buys 13 bottles of apple juice at the corner store for a total cost of $9.23. Assume each bottle of juice is the same price. If c represents the total cost in dollars and cents of the juice for any number, j, of bottles of juice, write a proportional equation for c in terms of j that matches the context.
Answer:
c = 13j × $0.71

In the diagram at the right..solve for x
Answer:
x = 11
Step-by-step explanation:
Since the 2 triangles are exact replicas of each other, we see the angle for this is 54 from the first triangle, and that 4x+10 is the angle as well.
So we set up the equation:
[tex]4x+10=54\\4x=44\\x=11[/tex]
